Preliminary Datasheet
1.6x Linear Fan Driver with Enable Function
General Description
The AP2113A is a low dropout high performance
linear regulator which is specially designed to drive a
DC fan, the regulator delivers output current 600mA
in minimum.
The AP2113A provides low quiescent current
consumption 70µA, and over current limit protection
and load short current protection with fold-back
limitation 50mA, which are ideal for battery powered
system application.
The AP2113A output voltage (V
OUT
) follows 1.6
times of V
SET
input voltage until it reaches V
IN
voltage m
inus
dropout voltage (V
DROP
). The V
SET
voltage must be larger than 1.0V to guarantee V
OUT
1.6 times of V
SET
. An Enable pin further reduces
power dissipation while shut down.
The AP2113A is available in standard SOIC-8
package.
